My son had a very questionable call at state last year. That call was the difference between placing and not placing. I don't know what my instant reaction was, but my reaction right after the match was explaining to my son that we don't blame a loss on a ref. If the match was that close that a call affected the outcome...he should have done something different so the match wasn't that close. My worst fear is my 7 year old thinking he lost a match because of a call. That creates a monster when they are 16 or 18 years old.
